Practical Minds.
Mr.. John G. Goodridge, Jr., has sug-
7ested project for modifying the climate
IF the Atlantic coast by closing the Strait
iof Bell Isle, and advances the theory that
This scheme is feasible as a problem in
nhvsical geography capable of an engi-
neering solution. He argues that it is
shown by chsrts that the great body of
fine "cold wall" comes to US through that
strait. Newfoundland defects the re-
mainder of the Arctic current to the
southeast. Here, pressing against the
Gulf Stream, it veers southwark in the
form Of loop, and finally, running QEp
der it, goes on toward the equator. Lat
mart of the Gulf Stream that passes Four
shores has a course directly north ande
little west, is detected slightly toward the
esst bY the coasts Of South and of North
Carolina, and thence turns more to the
north again, when it is detected by the
cold current returning from the pole.
when this cold current is of least
strength, as in August and September,
4ba Gulf Stream comes within ten miles of
Raruegat; at other times it is distant l20
miles, changing with the amount of the
cold current and of the wind. If We had
fine Gulf Stream, it is fair to presume
that we should have less stormy coast,
as the iuxtaposition of these two currents
with their difference in temperature must
from that circumstance tend to an I'M
stable condition of atmospheric equiIib-
rum. Our cold northwest winds would
then sweep to the north of US and become
westerly and southwesterly Winds Pop

DIR. George M. Sternberg confirms, in q
communication to the Johns Hopkins
University, as result of his own Obser-
walton, Laveran's discovery of the germ,
er miCro-organism, of malaria. LaVeran
found this microbe III the shape OF an
ameboid parasite in the blood OF patients
suffering from fever. and also observed
that the germs disappeared from the
blood when Quinine was administered IN
effective doses. During q recent visit TO
Rome DIR. Sternberg wss present at
most satisfactory demonstration OF the
presence and am9boid movements of the
parasitic in blood drawn from the finger Of
q patient in the first stage Of malarial
naroxvsm. Types of intermittent fever
mad been induced in previously healthy
nersons by injecting into the circulation
aasmell quantity Of blood drawn from 8
maIariaI patient during his fever. The
presence of the parasite in the injected
blood was demonstrated, and it was found
again in the blood of the persons subjected
TO the experiment during the induced in
termittent psrOXysms. These parOXysms
were arrested, and the parasite disap-
peared from the blood when quinine was
administered.

70 lace rubber belts properly: The belts
should be placed on the pulleys as tight
as possible. This can best be done by
the use of belt clamps, except IN the case
of very narrow belts. In all cases the
belt should be cut about One-eighth of an
inch less than the distance around the
pulleys with q tape line. The seam of the
belt should always be on the outside. For
narrow belts QUIT the two ends together,
make two rows of holes in each end, thus
obtaining double hold, and lace with
laCe-Ieather. For wide belts put in addi-
ton on the back a strgng piece of leather
or rubber, and sew or Tivet it TO the belt.
, # the belt should slip it should be lightly
tmOistened with boiled linseed oil; animal
oil will ruin the belt. If one application
does not produce the desired result repeat
until it does The belts will be greatly
improved and their durability increased
by coating. the surface lightly with COM
position maze Of equal parts Of black
lead and lItharge mixed with boiled lin
seed Oil and Japan, enough to cause it to
dry quickly; the effects of this will be to
produce finely polished surface.
To build chimney hat will, draw for
ever and not fill up with SCOT, you must,
build il large enough, sixteen inches
square; use good brick, and clay instead
of lime up to the comb; plaster it inside
with clay mixed with salt; for chimney
tops use the very best of brick, wet them
and lay them in cement mortar. The
chimney should not be built tight to
beams or rafters, as most chimneys settle
8 little, and if too tight between the beams
and Tafters, there is where the crack in
your chimneys comes and where the most
Of the fires originate, as the chimney
sometimes gets red hot. A chimney
built from cellar up is better and less
dangerous than one hung on the wall.
Don't get your stovepipe hole so close to
the ceiling, eighteen inches from it.
The Builder.
In dealing with q cellar in springy
ground, the first thing to be done to make
it dry, says the Sanitary Engineer, is to
provide some chance for the water to run
sway before getting into the cellar. This
may be done by laying a two-inch tile
drain pipe in trench dug all around the
foundation outside of the walls, and from
one foot to two feet below the cellar floor.
Put this pipe together withoutmortar and
cover it with cobblestones to keep out the
dirt and sand. If 1t be not practicable to
lay the drain outside 1t may be laid inside
Of the cellar walls, directly in the cellar
floor; but the operation of such drain is
less efficient. The backflling of the Gel
lar walls should be porous enough to allow
the water to go directly into the drain.
The Guide Scientiique gives the follow
ing method of making artificial whet-
stones: Gelatine of good quality is dis
solved in its own weight OF water, the
operation being conducted in dark room.
To the solution II per cent. of bichromste
of potash is added, which has previously
been dissolved in little water. A guam
tity of very fine emery, equal to nine
times the weight of the gelatine, is init
mRtely mixed with the gelstine solution.
Pulyerized flint may be substituted for
emery. The mass is nodded into any
desired shape and is then consolidated by
